Answer:
x = 1/6
Step-by-step explanation:
2(3x+1)=3
Distribute.
6x + 2 = 3
Subtract 2 from both sides.
6x = 1
Divide by 6 on both sides.
x = 1/6
Answer:
Mean of boiling times = 26.9 seconds
Step-by-step explanation:
Times ella recorded are given as;
24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.
Now, we want to find the mean of these boiling times.
Formula for mean is;
Mean = sum of terms/number of terms
In this question,
number of terms = 4
Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6
Thus,
Mean = 107.6/4
Mean = 26.9 seconds
